Sensors and Transducers

A transducer is a device that converts one form of energy into another, often for the purpose of measurement or information transfer.Transducers are commonly used in automation, measurement, and control systems.Here are some examples of transducers: - Microphone: Converts sound waves into electrical signals- Loudspeaker: Converts electrical signals into soundwaves- Thermometer: Converts energy into a form that can be measured- Position and pressure sensors: Convert energy into a form that can be measured- Antenna: Converts energy into a form that can be measuredThe process of converting one form of energy into another is calledtransduction.The Block Diagram is shown here.
